While Elizabeth Olsen and Tom Hiddleston have some intense on-screen chemistry in the Hank Williams biopic I Saw the Light, the 27-year-old actress says that their relationship is purely professional.

Olsen sat down with ET at a press junket for the upcoming biographical drama, where she dismissed rumors that the two have struck up a real-life romance as "a bunch of strangers saying a bunch of stuff that they don't know about."

However, she had nothing but praise for her handsome co-star, explaining how she and Hiddleston "really work really well together." Though the two are both stars of the Marvel cinematic universe – Olsen joined the Avengers as Scarlet Witch in 2015's Age of Ultron, while Hiddleston plays Thor’s troublesome half-brother Loki – they have yet to share the screen in a comic adaptation.

"I would love to work with him again," Olsen gushed. "He's such an incredible person. Anyone who's worked with him knows how disciplined and rigorous he is, and kind and respectful."

In I Saw the Light, Hiddleston plays famed country crooner Hank Williams, while Olsen plays the singer’s first wife, Audrey Williams. The couple's tumultuous eight-year marriage ended in an acrimonious divorce in 1952, a year before Williams died at the age of 29.

Despite their dramatic and intense on-screen relationship, Olsen said her time on set with Hiddleston and director Marc Abraham was the "most creative environment I've ever been in."

"With that kind of safety you're allowed to have intimacy," she explained. "you're able to listen to someone and be present within a film together."

Olsen also opened up about her famous older twin sisters, Mary-Kate and Ashley, and why her career in show business began so much later in life than theirs.

"It wasn't until I was 15 where I felt confident enough to say [acting is] what I wanted to go to college for," said Olsen, who didn't make her big-screen debut until 2011, when she broke out with an acclaimed performance in Martha Marcy May Marlene.

According to the actress, her sisters' best advice when it came to her career was to just finish school. Although she admitted that they "probably told me things that I didn't listen to."
